Adolescent Diabetes Is On the Rise
Here’s What Parents Should Know
I BY MEGAN CONWAY
Newton points out that even prior to the
pandemic, the number of Type 2 diabetes in the
under-20 U.S. population was increasing at an
alarming rate (2). The University of Maryland
Medical Center noted a “statistically significant
increase in … children and adolescents less
than 20 years of age newly diagnosed with
diabetes (over the last year),” with most of this
increase driven by an increase in the rate of
Type 2 diabetes.

n recent years, health experts have noted
rising rates of diabetes, both among the
general population and in adolescents.

We spoke with Dr. Paula G. Newton,
director of pediatric endocrinology at the
University of Maryland Center for Diabetes and
Endocrinology, and Dr. Brynn Marks, pediatric
endocrinologist at Children’s National Hospital,
to find out more adolescent diabetes.

Overview Two types of diabetes exist: Type 1 and Type
2. According to Newton, “Type 1 diabetes is an
autoimmune condition where your immune
system—which is supposed to fight germs,
bacteria and things that make you sick—
instead starts attacking (your pancreas). Your
pancreas can no longer make insulin.” As a
result, an individual’s blood sugar increases.

To address this increase, a person must treat
this condition with insulin.

Marks adds, “While the exact cause of Type
1 diabetes is unknown, viral infections are
thought to be a possible trigger in genetically
susceptible individuals.” This disease, she
explains, develops in stages.

Newton reports, “Type 2 diabetes is more
related to weight, exercise and diet. When
people are diagnosed with Type 2 diabetes,
often their pancreas can still make insulin—and
often makes an increased amount of insulin—
but it is still not enough to keep … blood sugars
in the normal range.” This type of diabetes,
Newton says, is usually initially treated with
insulin. However, “as the blood sugars improve
and (patients) make lifestyle changes, many can
decrease the amount of insulin required and can
utilize more oral medications.”
Risk factors and health
consequences Risk factors for diabetes depends on the type.

Newton points out that those with Type 1
diabetes have a greater likelihood of having
a family member with other autoimmune
conditions. People with Type 2 diabetes are
more likely to have a parent or close member
of the family with insulin resistance or Type
2 diabetes.

In addition, Newton says, “The risk of Type
2 diabetes (differs with) race and ethnicity,
with American Indians, African Americans and
Latinx (individuals) being most at risk.”
Age also contributes to risk. “Type 2 diabetes
is more common in people over age 10 and
those … in puberty as compared to younger
children.” Finally, a major Type 2 diabetes risk
factor is lifestyle. Weight gain, lack of exercise
and eating high-calorie and high-fat foods in
large amounts are contributing factors.

Newton further explains, “Adolescents with
Type 2 diabetes are at increased risk for other
metabolic conditions such as high cholesterol
and high blood pressure,” and “complications
of persistent high blood sugars such as visual
impairment, kidney disease and neuropathy
(numbness, weakness and pain in the feet
and legs).”
Current trends
Prevention and screening
The Centers for Disease Control and
Prevention reports no current known cure
for Type 1 diabetes, but Marks notes, “With
insulin therapy and recent developments in
Type 1 diabetes technologies, we are able to
successfully treat Type 1 diabetes and people
can live near normal lives.”
Several lifestyle changes can help individuals
prevent Type 2 diabetes. Marks advises, “Staying
active and eating a healthy, well-balanced diet
can help to maintain normal glucose values.”
Newton recommends that the family
contribute to meal planning that includes
choosing fruits and vegetables in lieu of high-
calorie, high-fat foods. Sleep is important, and
Newton reports that a consistent eight to 10
hours a night is optimal for children in school.

Parents should look out for potential
concerning signs of diabetes, says Newton,
which include, “increased thirst, increased
urination, bedwetting in a previously dry child,
sudden unexplained weight loss and gastroin-
testinal symptoms such as persistent vomiting.”
If parents notice these symptoms, Newton sug-
gests first contacting your child’s pediatrician.

If screening indicates a concern for diabetes or
pre-diabetes, your child will be referred to a pedi-
atric endocrinologist for further treatment. n
According to Newton, one in 400 people
younger than age 20 have Type 1 diabetes.

“The incidence in minority populations
(African American and Latinx communities)
has shown a slight increase over the past
several years,” Newton says.

“At Children’s National, we saw an increase
in both cases of Type 1 and Type 2 diabetes
over the last three years,” notes Marks (1).
